YJJ MPn-4C Combustible Gas Sensor Is Used As A Gas Leakage Detector In Various Places

Features:

MPn-4C is manufactured using a multi-layer thick-film manufacturing process. It integrates heating electrodes, measurement electrodes, and a metal oxide semiconductor gas-sensitive layer on an Al2O3 ceramic substrate, and encapsulates it in a metal housing. When there is a detected gas in the ambient air, the conductivity of the sensor will change. The higher the concentration of the gas, the higher the conductivity of the sensor. A simple circuit can convert this change in conductivity into an output signal corresponding to the gas concentration. This product has excellent anti-interference ability for common gases such as alcohol and acetic acid in the usage scenarios, such as gas leak monitoring devices for homes, factories, and commercial use, fire prevention/safety detection systems; gas leak alarms, gas leak detectors, etc.
